Be it known vthat I, `TIMOTHYSTEBBI`Ns,-a citiZen-offthenUnited States, `anda resident of Davenport,-in the `county-of Scott and State ofIowa, have invented certain new and usefullrnprovements in Puppet-Valves, of which the-f following .is 1 a' full, clear,l and exact description, referencebeinghad to theaccomi' Y panying drawings.

My invent-ion' relates to puppet-valves and its -objectisto provide meansI for retaining thesame in its seat undernormal conditions, which insures* the proper action of the valve to'openand closethevalve-opening and -yet I5 permits the:v removal of the valvefrom'its seatg by fwithdrawing it vertically whenever forfrepairsvor other reasonit is desirable' to;

dorso'. fThisl accomplish by themeans hereinafter fully described kand as particularly pointed outin' therclaims.

VIn the drawings,Figure 1 isa side .view of myf-i'nvention andvalve-seat therefor and pipe, whieh i's vinf-section 'and to which said invention isappliedL J Fig.- 2 is -a plan of the undersid'eof the same 'removed fromthelk pipe.. Fig. 3 is-avertical central section thereof. Fig. ,ll-is .a detailfview of one of the spring-yokes vused in'A connection withsaidy valve and removed' therefrom. Fig. 5 is fa side-viewof'.thefholder of the valve separate frorn theother; parts 'of' the same. Fig.r 6V is aplanview of the same. Fig. 7 is a side view ofthetop plateof said valve.

'iT-hef valve shown in the drawings comprises a circulary -or other suitably-shaped plate A, whichlform's the back of the valve, and:V is pro-l vided with4 a screw-threaded stud a, projecting upward from the center thereof. vProj ecting downward from the center of plate A isal short screw-threaded stud B, which is in alinementwith and is greater'in diameter than s tu'd a,`r which is preferably made hollow ory core'd,'=so that the lower edges thereof. may be spread outward to assist inA` locking the yoke holder' O thereto, las will hereinafter more fully appear. This lholder comprises a Washer-shaped body offless diameter than the opening' the -valve closes, andf its upper. portion/isk stepped to al lessdiameterto form a' seat-for thefqinnerl yedges of the packing-ring D; of rubberor other suitable material,v whichy isclamped between the lowercir'cumferential flange l thus f formed Aand .the Aunder side of plate JA, `where1 said holder; is screwedthome upon said stud Bas'farf asit-will go. .The inner circumferenceofthebody of the holder is providedwith four e'quidistant-longitudinal groovesl c @,theupper f' ends of whicht extend radially outward. IThesegrooves c form seats for. the endsveze of theuyokesEv'fandF.V :The lower portions of the yokesxconformlto the outlines off a *heart-,shaped `igure l but the ends e thereofl curve inward fromv the upper anglesk or. shoulders f f andthen upwardV in .y

gradually-converging planes iii-:grooves c, and their upper extremities arebent radially outward/and' rest". and' are: coniined inthe upper portionsof said-grooves. iYokes'E and'F are arrangedV atl right angles* to each other, and the. point of one is. given-a reverse curve,=so

ends of each yokefare-seated` inoppositelylo ,catedgroovesd fand when inthe proper posi# tion-'and the holder is screwed home konwstud stud outward in any suitable manner. Be-

tween the-.portion of-theends of thek yokes seated inthe grooves! c of the holder-and the shoulders f of the sar'nethe yokesrest'i-n and against the channeled inner side Of-lugsg g, projecting `downward from the -under siderof the holder, so that their channeled inner edges aline with grooves c.

his valve is seated -ina bushingsG, which is screwed into `the restricted opening of the well-pipel at thefpoint therein-wherethe said yvalve is-located,' land'when forced down `intoplacethe'yokes'spring-inwardas they l pass through' the, valve-opening inthe bushing-and then spring outwardto their Voriginal position again when below the same. :The spread of the shouldersofv the yokes is such that they catch under the edge of the restricted opening ofthe bushing, and ititakes more than the ordinaryv 'lift to removethe rvalve from its seat. :In orderto prevent the valve fromtipping to one sidewhen in action, the

as to arch over the point of the other. .The

outer' edgesl of'lugs g g-.are `preferablyY ad-j vancedslightly-.beyond the circumferenceof the body of the yokeholder'and' aremade perpendicular orf parallel to the 'axis fofr the valve. x v v What'l claim as'newis* .y 1.
